Proportional air valves

Proportional flow control valves feature 250 Hz frequency response with low hysteresis in nine orifice sizes from 0.32 to 0.625 in. for pressures to 120 psi Isolation diaphragm separates working fluid from coil and armature to limit fluid path exclusively to the poppet area. They are suitable for gases and liquids and come in anodized aluminum with nitrile elastomers. Lack of rubbing contact surfaces eliminates sliding friction, allowing them to operate proportionally on straight dc electrical signal with no dithering.
